The Impact of Powassan Virus and Borrelia burgdorferi Coinfection in Ixodes scapularis Ticks
… significant pathogens. Two of these include Powassan virus (POWV) and the spirochete Borrelia burgdorferi, both of which are transmitted by Ixodes scapularis in the northern parts of the United States. Powassan virus can lead to neuroinvasive illness with a high fatality rate. B. burgdorferi …

Ecology and Climate Tolerance of Emerging Tick Disease Vectors in Central Appalachia/Southwestern Virginia
… agent of human granulocytic anaplasmosis), and Powassan virus (the causative agent of Powassan encephalitis) were detected in collected field specimens, suggesting a significant threat to public health. The detection of Powassan virus RNA in local Ixodes scapularis ticks is the first evidence of …

Role of <i>Ixodes scapularis</i> Sphingomyelinase-Like Protein (IsSMase) in Tick Pathogen Interactions
… in arthropod-borne disease transmission. Langat virus (LGTV) is a model pathogen that is very similar to other medically important flaviviruses such as Tick-Borne Encephalitis virus (TBEV) and Powassan virus (POWV). Sphingomyelinase-like protein (IsSMase, a Sphingomyelinase D or SMase D, a …

Characterization of Flavivirus-Infected Neurons
Powassan virus (POWV) is a tick-borne flavivirus (TBFV) that can cause severe encephalitis in humans with a case fatality rate as high as 15%. Patients who survived severe encephalitic disease can develop long-term sequelae that can be debilitating and life-long. In this dissertation, a primary …

Evaluating the Prevalence of Tick-Borne Viruses Circulating in Virginia Using a One-Health Approach
… pathogens, including bacteria, protozoa, and viruses, to vertebrates. In the United States, tick-borne pathogens are responsible for around 95% of arthropod-borne diseases. Lyme disease is the most common tick-borne illness. However, emerging tick-borne viruses such as Bourbon virus (BRBV), …

Environmental factors affecting the range expansion of Ixodes scapularis, the blacklegged tick, (Acari:Ixodidae) in Illinois
… the disease agents of Anaplasmosis, Babesiosis, Powassan virus disease, Ehrlichiosis (Ehrlichia muris eauclairensis), Borrelia miyamotoi disease, and several strains of spirochetal bacteria which can cause Lyme disease. Both the human prevalence of Lyme disease and distribution of I. scapularis …

THE EFFECT OF BIOTIC AND ABIOTIC FACTORS WITHIN THE SOIL ENVIRONMENT ON THE MORTALITY OF IXODES SCAPULARIS DURING THEIR OFF-HOST PERIODS
… States, including anaplasmosis, babesiosis, Powassan virus, and Lyme disease. This species spends most of its two-year life cycle either questing for hosts on leaf litter and low-lying vegetation, or inactive during non-questing periods in the soil. Despite the prolonged periods this species …

Human Antibody Response to Flaviviruses and SARS-Coronavirus-2
… outbreaks. These include tick-borne encephalitis virus (TBEV), Powassan virus (POWV), Zika virus (ZIKV) and severe acute respiratory syndrome coronavirus (SARS-CoV-2). The first part of this thesis focuses on encephalitis-causing tick-borne flaviviruses, specifically TBEV and POWV. Both TBEV and …

One tick closer to a better understanding of tick physiology and how to incorporate tick biology in a classroom
… include the causative agents of Lyme disease and Powassan virus disease. Due to various human impact factors such as global climate change, black-legged ticks have been expanding their range and establishing themselves in new areas, allowing them to encounter novel animal hosts as well as new …

The Spatial and Molecular Epidemiology of Lyme Disease in Eastern Ontario
Lyme disease is an emerging tick-borne illness in Canada, with human case numbers increasing 15- to 20-fold since Lyme disease became nationally notifiable in 2009 until the present. In Ontario, Canada's largest province by population, average Lyme disease incidence across the province is similar …
